Chris@1072: Changes in Sonic Visualiser 2.5 since the previous release 2.4.1:
Chris@1072: 
Chris@1072:  - Add unit-converter dialog, for converting between various pitch and
Chris@1072:    timing units
Chris@1072: 
Chris@1072:  - Fix failure to reload note layers from session file
Chris@1072: 
Chris@1072:  - Use a more sensible scale for the play-speed dial
Chris@1072: 
Chris@1072:  - Fix crash when importing very wide CSV files
Chris@1072: 
Chris@1072:  - Fix generation of wrong layer type from some CSV files
Chris@1072: 
Chris@1072:  - Fix failure to export last instant in a time-instant layer
Chris@1072: 
Chris@876: Changes in Sonic Visualiser 2.4.1 since the previous release 2.4:
Chris@876: 
Chris@876:  - Fix a crash when rendering certain colour 3d plot layers
Chris@716: 
Chris@714: Changes in Sonic Visualiser 2.4 since the previous release 2.3:
Chris@714: 
Chris@776:  - Add support for left/right scrolling using a two-finger touchpad
Chris@776:    gesture (where available)
Chris@776: 
Chris@716:  - Make the octave numbering into a configurable option, and change
Chris@716:    the default. Previously Sonic Visualiser labelled middle-C as "C3";
Chris@716:    now it labels middle-C as "C4", a more common standard in the world
Chris@776:    outside MIDI sequencer software. The previous system is available
Chris@776:    as an option in the Preferences. This affects only the visible
Chris@776:    labels: there is no change to analysis or to the file format
Chris@714: 
Chris@714:  - Sonify time-value layers. Any time-value curve whose scale unit is
Chris@714:    set to Hz will now acquire a playback toggle control; this control
Chris@714:    is off by default, but if it is switched on, the curve will be
Chris@714:    played back using a variable-frequency sound generator
Chris@714: 
Chris@714:  - Add support for playback of note layers with non-MIDI frequencies
Chris@714:    (formerly the note playback was limited to exact MIDI pitch)
Chris@714: 
Chris@714:  - Change the default playback sample for note layers from piano to an
Chris@714:    electric piano with sustain. The piano sample is still available,
Chris@714:    and any sessions saved using it should continue to use it
Chris@714: 
Chris@867:  - Add a cancel button for Vamp plugin processing: currently,
Chris@867:    cancelling a transform results in a part-complete layer rather than
Chris@867:    removing the results
Chris@867: 
Chris@790:  - Add keyboard shortcuts to cycle the current layer (in addition to
Chris@790:    the existing ones to cycle the current pane)
Chris@790: 
Chris@790:  - Fix various bugs related to layer ordering: layer tabs re-ordering
Chris@790:    themselves randomly when new layer added, layers being ordered
Chris@791:    randomly when saving and reloading a session
Chris@790: 
Chris@848:  - Fix incorrect interaction with non-Unicode usernames when creating
Chris@848:    temporary and template directories on Windows
Chris@848: 
Chris@714:  - Shade the start and end of the main audio file, to make them easier
Chris@714:    to see for files that start or end in silence
Chris@714: 
Chris@714:  - Speed up rendering and scrolling in time-value layers
Chris@714: 
Chris@714:  - Make it possible to import CSV files directly into Note layers by
Chris@714:    adding Pitch as a data type in the CSV file import dialog
Chris@675: 
Chris@856:  - Fix play pointer jump to wrong frame when clicking on row in the
Chris@856:    layer edit dialog
Chris@856: 
Chris@848:  - Fix problems with keyboard shortcuts when using Qt5 on OS/X. This
Chris@848:    is the first release in which the official builds use Qt5 for all
Chris@848:    platforms.
Chris@848: 
Chris@675: 
Chris@675: Changes in Sonic Visualiser 2.3 since the previous release 2.2:
Chris@675: 
Chris@675:  - Add a startup welcome dialog that also explains what SV makes
Chris@675:    network connections for and allows user to forbid them
Chris@675: 
Chris@675:  - Add "Export Audio Data" feature
Chris@675: 
Chris@675:  - Show piano keyboard scale in note and time-value layers as well
Chris@675:    as spectrogram, where vertical scale is log Hz; also show
Chris@675:    numerical scale in note and region layers when not auto-aligned
Chris@675: 
Chris@675:  - Speed up CSV file import and avoid showing crazily wide window
Chris@675:    for CSV file format dialog when file has lots of columns
Chris@675: 
Chris@675:  - Fix incorrectly saved window geometry when exiting from maximised
Chris@675:    state
Chris@675: 
Chris@675:  - Reduce number of timer wakeups when idle
Chris@675: 
Chris@675:  - Add American English translation and make choice of translation
Chris@675:    into a preference (defaulting to system locale)
Chris@675: 
Chris@675:  - Permit installation to non-default location with Windows installer
Chris@675:    build
Chris@714: 
Chris@608: 
Chris@608: Changes in Sonic Visualiser 2.2 since the previous release 2.1:
Chris@608: 
Chris@608:  - Build with support for hidpi ("retina") text on OS/X
Chris@675: 
Chris@608:  - Fix very slow analysis when using Ogg or FLAC files decoded
Chris@608:    via libsndfile
Chris@675: 
Chris@608:  - Fix inaccurate scale auto-align between time-value layers and
Chris@608:    others
Chris@675: 
Chris@608:  - Fix failure to open files specified on command line (or via
Chris@608:    Open With) on Windows
Chris@675: 
Chris@608:  - Reset cyclical counters and switch back to navigate mode when
Chris@608:    a new session is started
Chris@579: 
Chris@675: 
Chris@579: Changes in Sonic Visualiser 2.1 since the previous release 2.0.1:
Chris@579: 
Chris@579:  - Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix)
Chris@675: 
Chris@579:  - Make it easier to see results from transforms that return a single point
Chris@675: 
Chris@579:  - Make labelling clearer on time-value layers
Chris@675: 
Chris@579:  - Add discrete-curve mode for time-value layers (for curves with gaps)
Chris@675: 
Chris@579:  - Update code to build against Qt5
Chris@523: 
Chris@675: 
Chris@523: Changes in Sonic Visualiser 2.0.1 since the previous release 2.0:
Chris@523: 
Chris@523:  - Fix incorrect samplerate in reading m4a files on OS/X
Chris@512: 
Chris@675: 
Chris@512: Changes in Sonic Visualiser 2.0 since the previous release 1.9:
Chris@512: 
Chris@512:  - Support 64-bit builds on OS/X (using CoreAudio instead of
Chris@512:    obsolete QuickTime audio file reader)
Chris@512: 
Chris@512:  - Simplify RDF reading and fix some bugs. Now requires Dataquay
Chris@512:    (http://breakfastquay.com/dataquay/) rather than using Redland
Chris@512:    directly. Release builds use Sord/Serd rather than Redland
Chris@512: 
Chris@512:  - Add a fullscreen mode on the F11 key
Chris@471: 
Chris@675: 
Chris@471: Changes in Sonic Visualiser 1.9 since the previous release 1.8:
Chris@471: 
Chris@471:  - Add session templates; save session as template; apply template to
Chris@471:    session
Chris@471: 
Chris@471:  - Tidy up the file open logic so as to remove the dialog asking how
Chris@471:    to open a file, where possible
Chris@471: 
Chris@471:  - Various bug fixes.
Chris@394: 
Chris@675: 
Chris@394: Changes in Sonic Visualiser 1.8 since the previous release 1.7.2:
Chris@394: 
Chris@394:  - Sonic Visualiser now registers as a file type handler on OS/X,
Chris@394:  providing better integration with the desktop generally (Dan Stowell)
Chris@394: 
Chris@394:  - There is a new function to toggle all Time Rulers at once (key #)
Chris@394: 
Chris@407:  - The CSV import dialog has been overhauled, allowing more flexible
Chris@407:  selection of purpose for each column
Chris@407: 
Chris@394:  - Text overlays are now easier to read on dark backgrounds
Chris@394: 
Chris@394:  - Hidden layers are now ignored when exporting an image (Dan Stowell)
Chris@394: 
Chris@394:  - A crash when starting a new session or exiting the application
Chris@394:    after loading a session with saved alignment data has been fixed
Chris@394: 
Chris@394:  - The duplication of right-button menu functions when multiple files
Chris@394:  were loaded has been fixed
Chris@394: 
Chris@394:  - The layer-add menu functions now have shortcuts (Dan Stowell)
Chris@394: 
Chris@394:  - The codebase has been reorganised into libraries and a configure
Chris@394:  step added.  It should be easier to build and maintain on OS/X and
Chris@394:  Linux than previously, although it won't make much difference on
Chris@394:  Windows.
Chris@394: 
Chris@397:  - A Czech translation is now included (thanks to Pavel Fric).
Chris@397: 
Chris@675: 
Chris@394: Changes in Sonic Visualiser 1.7.2 since the previous release 1.7.1:
Chris@394: 
Chris@394:  - The time-value layer now has an origin line and an option to
Chris@394:  show derivatives (change from one point to the next) rather than
Chris@394:  raw values
Chris@394: 
Chris@394:  - A static initialiser race has been fixed, possibly fixing an
Chris@394:  occasional crash on startup in Windows
Chris@394: 
Chris@394:  - A crash when pressing Play straight after New Session has been
Chris@394:  fixed
Chris@394: 
Chris@675: 
Chris@394: Changes in Sonic Visualiser 1.7.1 since the previous release 1.7:
Chris@394: 
Chris@394:  - The RDF importer does a better job of assigning labels to layers,
Chris@394:  layers to panes, and values to labelled regions
Chris@394: 
Chris@394:  - Interactive editing in the Text layer benefits from the same
Chris@394:  improvements as made in 1.7 to Note and Region layers
Chris@394: 
Chris@394:  - The layer data editor window has a text search feature
Chris@394: 
Chris@394:  - The main window status bar now shows the last label to have passed
Chris@394:  the playback position in the current layer, at the right end of the
Chris@394:  status bar
Chris@394: 
Chris@394:  - The Russian translation has been updated (thanks Alexandre)
Chris@394: 
Chris@675: 
Chris@394: Changes in Sonic Visualiser 1.7 since the previous release 1.6:
Chris@394: 
Chris@394:  - A new "Insert Item At Selection" function on the Edit menu
Chris@394:  can be used to create Note and Region layer items whose time
Chris@394:  extents correspond to the current selection(s)
Chris@394: 
Chris@394:  - Interactively editing points in the Note and Region layers
Chris@394:  now works much more smoothly
Chris@394: 
Chris@394:  - SV can now import MIDI files that use SMPTE timecode for event
Chris@394:  timing (importing MIDI files using with the more common
Chris@394:  timebase-based timing was already supported)
Chris@394: 
Chris@394:  - Time values throughout the display may optionally be shown in
Chris@394:  seconds and frames at various frame rates
Chris@394:  
Chris@394:  - A crash on exit in Windows has been fixed
Chris@394: 
Chris@394:  - A very unobtrusive user survey is now included
Chris@394: 
Chris@394:  - Various other bug fixes.
Chris@394: 
Chris@675: 
Chris@394: Changes in Sonic Visualiser 1.6 since the previous release 1.5:
Chris@394: 
Chris@394:  - The Colour 3D Plot layer now supports logarithmic vertical
Chris@394:  scale and linear interpolation options.
Chris@394: 
Chris@394:  - A new colour scheme (High Gain) has been added for spectrogram
Chris@394:  and Colour 3D Plot, which improves readability for some data.
Chris@394: 
Chris@394:  - Further performance improvements have been made to Colour 3D
Chris@394:  Plot.
Chris@394: 
Chris@394:  - Various other bug fixes.
Chris@394: 
Chris@675: 
Chris@394: Changes in Sonic Visualiser 1.5 since the previous version 1.4:
Chris@394: 
Chris@394:  - You can now insert time instants, time values, and notes using
Chris@394:  a MIDI device during playback.  If a time value or note layer is
Chris@394:  current it will be used for insertion (giving a value equal to
Chris@394:  the pitch class, or the played note, respectively); otherwise an
Chris@394:  existing or new time instants layer will be used just as it is
Chris@394:  when inserting instants using the PC keyboard.  Using a MIDI
Chris@394:  device should give better timing than using the PC keyboard.
Chris@394: 
Chris@394:  - There is a new Activity Log window with a (purely informative) list
Chris@394:  of events and user interactions that happen while SV is running.
Chris@394: 
Chris@394:  - The spectrogram has somewhat improved graphical scaling, and
Chris@394:  this is now the default (being much faster than the 4x oversampled
Chris@394:  method).  The previous default is still available as a preference.
Chris@394: 
Chris@394:  - Visualisation of very dense colour plots (such as spectrograms
Chris@394:  calculated by plugins) is substantially faster in this release.
Chris@394: 
Chris@394:  - Spectrogram display is now faster in many circumstances.
Chris@394: 
Chris@394:  - Alignment using the MATCH plugin is faster on OS/X than before.
Chris@394: 
Chris@394:  - SV will take into account RDF plugin descriptions, if available,
Chris@394:  in order to make somewhat better decisions about display of plugin
Chris@394:  outputs (for example, placing segmentation data into a layer with
Chris@394:  segmentation plot type).
Chris@394: 
Chris@394:  - You can now switch layers by clicking on the spare area at the left
Chris@394:  end of the pane that is also used for the current pane indicator.
Chris@394: 
Chris@394:  - The vertical black lines dividing segments in the time value
Chris@394:  layer's segmentation plot style are now optional.
Chris@394: 
Chris@394:  - Several widget layout bugs on OS/X have been fixed.
Chris@394: 
Chris@394:  - Several serious crashing, deadlock, and data corruption bugs have
Chris@394:  been fixed.
Chris@394: 
Chris@394: 
Chris@394: New features in Sonic Visualiser 1.4 since the previous version 1.3:
Chris@394: 
Chris@394:  - SV now has a Region layer type, used for display of features with
Chris@394:  durations.  It also supports Vamp v2.0 plugins that provide durations
Chris@394:  for features.
Chris@394: 
Chris@394:  - Layer data can now be imported from RDF described using the Audio
Chris@394:  Features Ontology, as well as from the existing text file types.  SV
Chris@394:  can also export annotation layer data to RDF/Turtle, although in a
Chris@394:  somewhat simplistic manner at present.
Chris@394: 
Chris@394:  - You can search for transforms by text in the new "Find a Transform"
Chris@394:  dialog.  This searches both installed plugins, and plugins that have
Chris@394:  not been installed but that have descriptions available on the
Chris@394:  semantic web.
Chris@394: 
Chris@394:  - You can now zoom and scroll vertically in the time-value, note,
Chris@394:  and colour 3d plot layers.
Chris@394: 
Chris@394:  - Sonic Visualiser can now load sessions from uncompressed XML files
Chris@394:  as well as its own compressed-XML .sv format.  Files with extension
Chris@394:  .xml that contain suitable session data will be loaded as sessions.
Chris@394:  Note that .xml extension files still do not show up in the default
Chris@394:  file load filter.  This is intentional, as there may be any kind of
Chris@394:  data in them -- if you want to load uncompressed session files from
Chris@394:  XML, you need to know you're doing it.
Chris@394: 
Chris@394:  - Several crashes and other bugs have been fixed.
Chris@394: 
Chris@675: 
Chris@394: Changes in Sonic Visualiser 1.3 since the previous version 1.2:
Chris@394: 
Chris@394:  - There is a new spreadsheet-style data viewer and editor for
Chris@394:  viewing and editing the data in some types of annotation layer.
Chris@394: 
Chris@394:  - Alignments are now saved to the session file.
Chris@394: 
Chris@394:  - The spectrogram layer is usually somewhat faster than it was.
Chris@394: 
Chris@394:  - You can now hold Shift while dragging to move an item, in order
Chris@394:  to override the initial drag resistance introduced in 1.2.
Chris@394: 
Chris@394:  - The gross mis-labelling of time lines in the ruler has been fixed.
Chris@394: 
Chris@394:  - There is a new, somewhat provisional PulseAudio output driver.
Chris@394: 
Chris@394:  - Several other bug fixes.
Chris@394: 
Chris@675: 
Chris@394: New features in Sonic Visualiser 1.2, since the previous version 1.0:
Chris@394: 
Chris@394:  - SV now supports time-alignment of multiple performances of a work
Chris@394:  loaded at the same time.  This option is enabled when the MATCH Vamp
Chris@394:  plugin is installed.  When alignment is switched on and more than one
Chris@394:  audio file is open, SV will assume that all open files are
Chris@394:  differently timed performances of the same work, and will calculate
Chris@394:  time alignments for them.  Playback will then play only a single file
Chris@394:  at a time, and the playback cursors in other files will track at the
Chris@394:  varying speeds to try to ensure that each is at the same point in the
Chris@394:  underlying score.  This enables effective comparison of several such
Chris@394:  files, as well as a meaningful way to switch from one performance to
Chris@394:  another during playback (ensuring that the switch happens at the
Chris@394:  correct point in the performance being switched to).
Chris@394: 
Chris@394:  - There is a new Image layer, which can display images from the
Chris@394:  local filesystem or retrieved via HTTP or FTP.
Chris@394: 
Chris@394:  - A new measurement tool has been added.  With the measurement tool
Chris@394:  selected, dragging in a pane draws a rectangle labelled with the
Chris@394:  scale values for its start and end corners and its size.  You can
Chris@394:  have any number of measurements present at once; they are associated
Chris@394:  with the top layer, their scale values depend on the scale for that
Chris@394:  layer, and they are only shown when that layer is at the top and the
Chris@394:  measurement tool is active.  Measurements are saved and reloaded in
Chris@394:  the session file.  Drawing measurements can be undone and redone, and
Chris@394:  a measurement can be deleted by hitting Del when highlighted.  Note
Chris@394:  that the measurement tool shows the scale values associated with the
Chris@394:  pixel positions of the mouse when dragging, not any values associated
Chris@394:  with actual features present in the audio or its analysis (e.g. the
Chris@394:  values are not rounded to the nearest spectrogram bin).
Chris@394: 
Chris@394:  - You can double-click using the measurement tool in the spectrogram
Chris@394:  to get an instant measurement rectangle for a feature.  This is a
Chris@394:  purely graphical feature that works by calculating the boundary of a
Chris@394:  contiguous region of pixels "similar to" the one you double-clicked
Chris@394:  on; it does not use audio analysis.  Adjusting the gain and colour
Chris@394:  scheme etc of the spectrogram will (by design) affect the
Chris@394:  measurements obtained this way.
Chris@394: 
Chris@394:  - The spectrum can now optionally show frequency estimates of peaks
Chris@394:  aligned with a piano keyboard along the horizontal axis (this needs
Chris@394:  some refinement).
Chris@394: 
Chris@394:  - The harmonic cursor in the spectrogram has moved from the Select
Chris@394:  tool to the Measurement tool.  There is now a similar harmonic cursor
Chris@394:  in the spectrum.  Both of them show more information as text
Chris@394:  alongside the cursor than previously.
Chris@394: 
Chris@394:  - There is a new Erase tool for erasing individual points from an
Chris@394:  editable layer.
Chris@394: 
Chris@394:  - Several keyboard shortcuts have changed -- all of the Alt+key
Chris@394:  shortcuts now either use Ctrl or a plain keypress with no modifier,
Chris@394:  to avoid clashes with window manager shortcuts and to make them
Chris@394:  easier to use and remember
Chris@394: 
Chris@394:  - The playback controls are now in a Playback menu as well as the
Chris@394:  toolbar.
Chris@394: 
Chris@394:  - There is a new key and mouse control reference under Help (or press
Chris@394:  F2).
Chris@394: 
Chris@394:  - You can double-click on a pane in navigate mode to jump to a time.
Chris@394: 
Chris@394:  - All of the single-colour layers (waveform, time values etc) now
Chris@394:  allow you to define your own colours as well as using the built-in
Chris@394:  set.  The colour of a layer is now shown next to its name on the pane.
Chris@394: 
Chris@394:  - When you add a new single-colour layer it will use a default colour
Chris@394:  that is not yet in use in another layer (if there is one).
Chris@394: 
Chris@394:  - Single-colour layers can now optionally have black backgrounds (with
Chris@394:  a set of lighter colours in the default colour palette that use black
Chris@394:  backgrounds by default).
Chris@394: 
Chris@394:  - There's a new Printer colour scheme in the spectrogram with only a
Chris@394:  small number of grey shades.
Chris@394: 
Chris@394:  - Vertical zoom in a log-scaled spectrogram is much more intuitive;
Chris@394:  it now leaves the point that was in the centre of the visible area in
Chris@394:  the centre after zoom, instead of the point that was in the centre of
Chris@394:  the linear range corresponding to the visible area.
Chris@394: 
Chris@394:  - You can now turn a colour 3d plot layer upside down by clicking the
Chris@394:  Invert Vertical Scale button.
Chris@394: 
Chris@394:  - There's a new Layer Summary window which shows the panes and
Chris@394:  layer data in a tree layout.  This is very simplistic at the moment.
Chris@394: 
Chris@394:  - Each pane now has an [X] button at its top left, which removes that
Chris@394:  pane when clicked.
Chris@394: 
Chris@394:  - There's a new Solo play mode toggle button; when active, only the
Chris@394:  currently selected pane is played.  This is also the default when
Chris@394:  time alignment is in use.
Chris@394: 
Chris@394:  - Rewind/ffwd now stay confined to the selection if Play Selection is
Chris@394:  enabled; also, the rewind and ffwd "one step" buttons are now enabled
Chris@394:  even if there is no time instants layer for them to align to (they
Chris@394:  align to the time ruler instead and so jump in steps of a size
Chris@394:  dependent on the zoom level).
Chris@394: 
Chris@394:  - You can now export note layers to MIDI.
Chris@394: 
Chris@394:  - MIDI note velocity is partially supported.  Note velocity is
Chris@394:  retained when importing and exporting MIDI and is used in playback,
Chris@394:  but it is not yet shown in the display and cannot yet be edited.
Chris@394: 
Chris@394:  - You can now drag-and-drop files (of whatever type) onto SV from
Chris@394:  other programs such as file managers or web browsers.
Chris@394: 
Chris@394:  - mp3 files (and Ogg, but they aren't supported on Windows at the
Chris@394:  moment) are now decoded in a background thread so you can see the
Chris@394:  start of the track without waiting for the rest to decode.
Chris@394: 
Chris@394:  - Mac builds of SV can now load AAC/mp4 files and anything else
Chris@394:  supported by QuickTime.
Chris@394: 
Chris@394:  - There is now an option to resample audio files on import if they
Chris@394:  don't match the samplerate of the first file loaded.  By default this
Chris@394:  is switched off, as it affects the visible waveform.  The default
Chris@394:  behaviour is unchanged (play at the wrong rate).  There is still no
Chris@394:  option to handle multiple rates "correctly" (i.e. by resampling
Chris@394:  on playback and showing the waveforms at different resolutions
Chris@394:  according to each one's underlying rate) and there probably never
Chris@394:  will be.
Chris@394: 
Chris@394:  - SV can now open .m3u playlist files, though it's a hazardous thing
Chris@394:  to do as it simply loads all the files in the playlist at once.
